Class sizes in highschool should be smaller

Hi, thank you for editing the last essay yesterday. Attached is the next essay. Please use exactly the same editing techniques. They were perfect.
Grade 12 essay, persuasive category. word count is fine 800 to 1000. MLA
Please help with transitions, better wording of thesis statement, and overall wording. I am especially having trouble with the conclusion paragraph. I am not sure if I actually persuaded anyone.
